Kirsten Johnson has expertise in a wide range of technologies, advising companies of all sizes from start-ups to multinational corporations on maximizing the value of their intellectual property. Kirsten has drafted and prosecuted hundreds of U.S. and international (PCT) patent applications, and coordinated with patent firms across the globe to obtain worldwide patent protection. She works with innovators to develop forward-looking strategies in line with their business objectives, employing patentability assessments, expedited prosecution strategies, and freedom-to-operate and due diligence analyses.

Kirsten’s expertise extends to diverse areas of innovation including chemical formulations, chemical and biochemical detection, pharmaceuticals, renewable energy, semiconductors, materials synthesis and characterization, cardiovascular prostheses, drug delivery systems, vaporizing devices, food products, health supplements, and personal care. In energy, she has worked with companies in a wide array of renewable technologies including fuel cells, solar cells, hydrogen, and biofuels. In biotechnology, she has experience in nucleic acid and small molecule detection for a variety of diagnostic and medical treatment applications. She has contributed to The Rose Sheet, a prominent publication in the cosmetics/fragrances/skincare industries, and IP Law360, a leading news source in the IP law community. A client tells The Legal 500, “she is excellent – a very good chemist, as well as a skilled patent lawyer.”

While earning her Ph.D. under the direction of Professor Mario J. Molina (1995 Nobel Laureate in Chemistry), Kirsten gained considerable hands-on experience in chemical kinetics, flow dynamics, aerosols, mass spectrometry, UV-Vis and X-ray spectroscopy, electron microscopy, and experimental design and optimization, including field work in Mexico City. She also has lab experience in high-pressure organometallic synthesis towards development of an HIV protease inhibitor, sol-gel production of nanoporous materials for bioremediation, and electrochemical research while studying abroad in Nantes, France.

Before joining Bookoff McAndrews, Kirsten was a technical specialist/patent agent at Finnegan while attending law school. During that time, she focused on prosecution and strategic portfolio management in pharmaceuticals and chemical formulations.
